My invention relates to a new and improved bracket for supporting a rear vision mirror on the upper front door hinge of an automobile on the drivers side in such away that it will be securely held against displacement the vibration of the vehicle and also by :ning andclosin'g of the door. Heretofore, such devices have been mounted on the ends of the hingepin of such a hinge, but since the ends of such a hinge pin atlord but a minimum ofholding surface, displacement of the bracket and a corresponding misadjustment of the rear vision mirror has been common. Y v

One of the mainobjccts of iny invention is to provide a constructionwhereby a much greater surface is afforded for the support of the bracket sothat displacement after application and adjustment is eilectively resisted.

'ln the accompanying drawings- 1 is a rear elerati'on of my bracket as applied to a hinge, certain parts being in section;

F 2 is a fragmentary View partly in seciion on the line 22 of Fig. 1;

Fig. 3 is a View similar to Fig. 1 showing a modification.

11 represents the two stationaryend hinge knuckles of a door hinge. 2 represents the intermediate rotatable hinge knuckle. 3 represents the usual hinge pin which passes through the several hinge knuckles in the usual way and upon which the knuckle 9. rotates.

In one form of my improved bracket, shown in Figs. 1 and 2, I provide an integral yoke member 4.- which has an arm 5 projecting laterally therefrom for supporting a rear vision mirror 6, or any other suitable device. The upper arm 7 of the yoke 4 is provided with passage for the hinge pin 3. This passage may be open at one side, as plainly seen in Fig. 2, to form a hook so that when the hinge pin is pushed up slightly to provide clearance above the upper hinge knuckle, this upper arm 7 may be hooked around the pin underneath the pin head which may then be knocked down so as to reston the upper 1929. Serial No. 411,177.

This obviates the necessity of entirely removing the pin 3 to apply the bracket. 't will be noted that in this position the lower end of the pin 3 stands slightly retracted within the lower stationary knuckle so as to' leave a recess therein. 8 is a clamping screw in the lower arm 9 of the yoke. This clamping' screw preferably has a slight projection 8 at its center which is adapted to ext-end slightly into the bore in the lower end of the lower hinge knuckle when the partsare assembled. The projection 8 which extends slightly into the bore of the lower hinge knuckle prevents lateral displacement of the lower end of the yoke from the hinge; A check nut 10 on the clamping 'screwB may be provided, if desired. it will now be that when the bracket is applied to the h V as shown in Fig. 1, the upper arm 5 orthe bracket takes abroad firm bearing'against the upper hinge knuckle around the pin passa-e, thus resisting'any turning movement of the bracket on the hinge- Lateral movement is prevented by the pin 3 which] passes through this arm 5. The clamping means '8' likewise takes a broad bearingagainstthe lower hinge leaf around the; pin passage, thus resisting a turning movement'of the bracket on the hinge and corresponding displacement thereof, while" tl1e p1'ojection 8 prevents the lower end of the yoke from being pulled oil laterally from thehingef It is, of course. immaterial whetherthehead of the pin 3 bears'upon the-upper end ot-the arm 5, since when the parts are 1 assembled the yoke is clamped tightly on the two errtreine ends of the endknuckles 11'o1t' the hinge. 7

, In the modification shown in Fig. 3, the yoke is formed in two parts l .and the upper end or the part 4: maybe shaped to correspond'with the upper end of 'the yoke which latter is carried by the yoke part P.

11 is a clamping nut on screw 11. Theilower arm of the lower'yoke piece 4 is shaped to fit against the lower end ottne lower hinge knuckle and preterably has'aslignt central pro ect1on 12 which extends. correspondingly into the bore of the lower hinge knuckle when the parts are assembled, performing the function of the projection 8 on the screw 8 (shown in Fig. 1). To assemble the parts shown in the modification, the clamping nut 11 is backed off until the two yoke sections -t" may be spread apart sufficiently to let their ends embrace the ends of the hinge to which the bracket is to be attached. The upper section 4? is then applied to the upper end of the upper hingeknuckle, as in Fig. 1, while the lower section 4 is applied to the lower end ofthe lower hinge knuckle. The clamping nut 11 is then screwed up .until the two parts 44 of the yoke grip on the ends of the hingein the proper adjusted position of the bracket, which is then firmly held against displacement the relatively large frictional surf-ace engagement of the ends of the yoke on the ends of the hinge knuckles.

From the foregoing, it will be seen that in a both forms of the bracket a maximum resistance to the turning movement is afforded so that the bracket will be efleotively held in the proper angular adjustment while lateral disengagement'of the bracket is absolutely prevented until the clamping means is backed off sufiiciently to permit the projection 8, in the first instance, and 12, in the second instance, to be removed from the pin passage in the lower knuckle.

I claim:

1. A bracket support for attachment to ahinge comprising, a yoke having ends overstanding the end knuclnes of a hinge and means to clamp said bracket to the outer.

ends of said end knuckles around the pin passage therein, the upper end of said bracket having a passage to receive that part of the hinge pin underneath the head thereof to hold theupper part of said yoke from disengagement from the hinge in a lateral direction, said passage being open at one side.

2. A bracket support for attachment to a hinge comp-rising. a yoke having ends overstanding the end knucles of a hinge and means to clamp said bracket to the outer ends of said end knuckles around the pin passage'therein, the lower clamping means of said bracket having an extension projectingslightly into the pin passage at the lower end of said lower hinge lea-f.

slightly into the pin passage at the lower end of said lower hinge leaf. 7

4. A bracket support for attachment to a hinge comprising, a one-piece'yoke having ends overstanding the end knuckles of a hinge, the upper end .of said yoke having a pin passage for the hinge pin, a movable clamping member at the lower end of said yoke for engagement with the lower end of the lower hinge knuckle around the pin passage therein, said clamping member having a portion to extend slightly into the lower end of said pin passage.

v5. A bracket support for attachment to a hinge comprising, a one-piece yoke having ends overstanding the end knuckles of a hinge, the upper end of said yoke having a pin passage for the hinge pin, a movable clamping member at the lower end of said yoke for engagement with the lower end of the lower hinge knuckle around the pin passage therein and having a portion to extend slightly into the lower end of said pin passage. V

6. A bracket support for attachment to ahinge comprising, aclamping yoke having its ends arranged to overstand the outer ends of the end knuckles of a hinge, one end of said yoke having a pin passage for the hinge pin, a clamping part at the other .end of said yoke for engagement with the outer part of the hinge knuckle adjacent thereto, one of the two last mentioned parts having a recess to receive within it a projecting portion of the other part to prevent lateral displacement of said yoke.
